DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a line output system for outputting character data in graphic coordinates in units of lines.

[0002]

2. Description of the Related Art Conventionally, character data in a graphic used in a computer system is displayed or printed in graphic coordinates with reference to an X coordinate and a Y coordinate. When displaying and printing, characters are displayed and printed in a graphic coordinate system called a plane, and are used as follows.

(1) Usage example 1: Character data in a figure depending on the resolution of a device for displaying and printing is created in advance and displayed and printed. (2) Usage example 2: The entire character data in a graphic created in usage example 1 is scaled (reduced or enlarged) and displayed or printed.

[0004]

For this reason, a display or printing device usually fixes all the sizes of characters to be displayed or printed uniquely as character data in a figure. Therefore, there is a problem that characters cannot be arranged according to the line space (density) at the time of display or printing. For example, at the time of display or printing, it is extremely difficult to arrange characters according to the line space (density, lpi) by external designation (external attachment) because it is necessary to search and rearrange all the character data in the figure. There was a problem that is.

An object of the present invention is to arrange a character string corresponding to an externally specified line space (density) without deteriorating display or printing performance for character data in graphic coordinates.

[0006]

FIG. 1 is a block diagram showing the principle of the present invention. In FIG. 1, record 3 is a record composed of line character data in a figure, a Y coordinate position, and the like, and generated in units of lines. The line space information 6 is information such as the number of dots per line, the vertical tab value, and the number of feed lines.

The line position determining mechanism 7 sets the Y coordinate position of the line character data in the figure in the record 3 based on the line space information 6.

[0008]

According to the present invention, as shown in FIG. 1, at the time of output, the line position determining mechanism 7 calculates the number of dots per line from the input line space information 6 and, based on the calculated number of dots per line, Set the number of dots corresponding to the Y coordinate value of the character data,
Characters are displayed or printed in an arbitrary line space (density, lpi). When the vertical tab value or the number of feed lines is set as the line space information 6, the dot corresponding to the vertical tab value or the number of feed lines is calculated based on the number of dots per line calculated by the line position determining mechanism 7. The number is set, and characters are displayed or printed at the position of an arbitrary vertical tab value or the number of feed lines.

Therefore, for character data in graphic coordinates, a character string corresponding to the externally specified line space information (density, lpi) 6 is arranged and displayed or printed without deteriorating the display or printing performance. Becomes possible.

[0010]

Next, the structure and operation of an embodiment of the present invention will be sequentially described in detail with reference to FIGS. In FIG. 1, an application program 1 is used to input one-line data of a character code or to specify a character attribute (character size, typeface, etc.) by a WRITE statement or an attribute definition statement.

The record (line character data in a figure) generation process 2 includes a WRITE command from the application program 1.
A record (line character data in a figure, see FIG. 2) 3 is generated based on one-line data of a character code specified by a sentence or an attribute definition sentence or a character attribute. The definition control information 4 is externally designated (externally attached) line space information for outputting the record 3.

The line space definition processing 5 includes the definition control information 4
From line space information (size of one page, line space,
Vertical tab values). The line position determining mechanism 7 merges the record (line character data in the figure) 3 and the line space information 6, that is, the number of dots per line calculated from the line space information 6 in the line space information 6, for example. The value of the Y coordinate of the character data in the figure is set, and the position of the character to be displayed or printed is determined.

The graphic output device 8 is a device for displaying or printing based on the in-graphic line character data output from the line position determining mechanism 7. Next, the operation of the configuration of FIG. 1 will be described. (1) The application program 1 requests the record (line character data in figure) generation processing 2 to generate a record (line character data in figure) 3 by a WRITE statement or an attribute definition statement.

(2) The record (line character data in figure) generation process 2 is based on the WRITE statement and the attribute definition statement notified from the application program 1 and, for example, as shown in a record 3 in FIG. A record 3 in which a line character code in a figure, a line identifier, additional information, a Y coordinate value, and the like are set is generated and stored in the memory 13. At this time, the record is generated for each row.

(3) The line space definition processing 5 generates line space information 6 from the definition control information 4 at the time of output. The line space information 6 includes a line space (density, lpi),
Vertical tab value, number of feed lines, etc.). (4) The line position determining mechanism 7 calculates the number of dots per line from the line space information 6, for example, space information (density, lpi) at the time of output, and based on the number of dots / line, the figure in the record 3 The Y coordinate value of the inner line character data is converted into a dot number and set.

(5) The graphic output device 8 displays or prints the in-graphic character data at the position corresponding to the number of dots of the in-graphic character data set in (4). By the above processing, the record 3 is calculated based on the number of dots / line calculated from the line space information 6 specified externally at the time of output.
The graphic output device 8 displays and prints the character data in the figure by setting the Y coordinate value of the line character data in the figure in the figure, and the line space (density, lpi ) Can be set externally and arbitrarily.

Next, a specific example will be described in detail with reference to FIGS. In FIG. 2, an input information designation mechanism (one line of character information) 11 designates one line of character information (character attribute) to be displayed or printed. Here, the attribute is specified in the attribute definition of the application program. The character data is designated by writing (WRITE instruction) of the application program. The attribute definition is specified as follows.

Character type specification (typeface) Character thickness specification Basic character size Character fixed magnification specification Character variable magnification specification Character fixed reduction specification Character variable reduction specification Character spacing specification Character direction specification Others In-figure line character data generation The process 12 sets other items from the input information for one line specified by the input information specifying mechanism 11 except for the setting of the line position (Y coordinate value). Here, in order to set the line position efficiently at the time of display or printing, an identifier indicating that it is line character data in a figure, information indicating a first record of a line, and the fact that a character string exists in a record are required. Information indicating the vertical tab value or the number of feed lines, information indicating the number of discontinuous character strings,
Information indicating the start position (Y coordinate offset) of the character string is set. This Y coordinate offset (Y offset)
This eliminates the need to search all of record 3
It is possible to quickly search only the part of the line character data in the figure.

The memory 13 is a memory (main storage device or external storage device) for storing the record (line character data in a figure) 3. The record (line character data in figure) 3 is stored in the memory 13, and the line space information 15 is externally pointed and stored in association with it. The line space information generating mechanism 14 includes line space information 15 representing the size of one page, the position of a vertical tab in the page, and the line space (density).
Generate

The row position determining mechanism 16 stores the row space information 1
5, the line position (Y coordinate) of the record (line character data in the figure) 3 is determined, and the graphic output device 17 displays and prints it. At this time, it is determined whether or not a character string exists in the record 3 on a line-by-line basis. If the character string exists, the Y coordinate is set if there is a setting offset of the Y coordinate (S in FIG. 3).
4). As a result, it is possible to set and output the Y coordinate only for a character string existing without searching all the records (line character data in a figure) 3 and to perform display and printing with less overhead.

Next, the operation of the configuration of FIG. 2 will be described in detail according to the order shown in the flowchart of FIG. In FIG. 3, S1 inputs one-row data as an initial input. 1
As line data input: ・ Character code ・ Character attributes (character size, font, etc.) are input.

In step S2, the character data in the figure is generated based on the character code and the character attribute. This means that the in-figure line character data generation processing 12 in FIG. 2 generates the record (in-figure line character data) 3 in FIG. 2 based on the one-line data input in S1. By repeating S1 and S2, records (line character data in a figure) 3 of FIG. 2 are sequentially generated in units of one line.

In step S3, the line space information 15 is fetched externally. In step S4, the number of dots per row is calculated, and the value of (rows × dots per row) is set as the value of the Y coordinate. For example, as described on the right side, 1440 dots per inch and 6 LPI (6 lines / inch), the number of dots per line is calculated as 1440/6 = 240 dots / line, and the record (line character in the figure) Data) 3 is multiplied by the number of rows to obtain the number of dots in the row, and set as a Y coordinate value.

In step S4, the output, that is, the record (line character data in the figure) 3 set in step S4 is output to the figure output device 17 for display and printing.

[0025]

As described above, according to the present invention,
A configuration in which the number of dots per line is calculated from the line space information 6 input at the time of output, the number of dots is set as the Y coordinate value of a record (line character data in a figure) based on this, and output (display or printing) is performed. , Character strings in the figure coordinates are easily arranged and displayed or printed according to the externally specified line space information (density, lpi) without deteriorating the display or printing performance. And so on.
Further, since it is not necessary to search all records (character data in a figure), the performance at the time of display and printing is not reduced.
